Q
UESTIONS
•
Are there quantity price breaks on stock items?
No. Stock items are manufactured in large quantities based on yearly sales. The “price break” is already in the stock
price list.
•
What’s the difference in Steel, Chrome and Carbide?
Gages are manufactured from
Tool Steel
and hardened to 58 - 62 Rc, unless specified otherwise by the customer.
Chrome
is a plating process that increases the hardness/wearablity and protects the gage from corrosion.
Carbide
is a sintered metal with a harder wear surface than Steel and Chrome with a comparable hardness of 79 -
81 Rc, but it is also brittle.
•
What is the difference between Adjustable Thread Rings and Solid Thread Rings?
Adjustable Thread Rings are as the name implies, adjustable. As the ring gage is used it will wear outside the allow-
able tolerance but can be re-adjusted back into tolerance increasing its wear life.
In the US, Solid Thread Rings are usually master rings used for setting Internal Thread Comparators.
Outside the US, the standard design of working gages is a solid ring. The Adjustable Thread Ring is an American
design.
•
What is A2LA?
A2LA is
The American Association for Laboratory Accreditation
.
This accreditation means an indpendant quali-
fied party audited and appraised GSG’s lab to ISO 17025.
A2LA is recognized throughout the world as a registrar for laboratories. GSG is one of very few gage manufacturers
that has this level of accreditation for our laboratories.
•
What are “Part Type Masters”?
Part Type Masters are used to set up gaging systems typically in a manufacturing line. Due to GSG’s unique capa-
bility to manufacture part masters with very close, gage-like tolerances, we have developed this market to serve
gage system manufacturers. Typical masters including brake drums, rotors, connecting rods, crank shafts, pistons
of all sizes, etc., are furnished to the auto industry, but many other industries can improve their processes by using
part masters.
•
What is API?
API is the American Petroleum Institute.
Typical specification include:
Spec 5B - Casing, Tubing & Line Pipe Threads
Spec 7 - Rotary Drill Stem Elements
Spec 11B - Sucker Rod
•
What is Helical Coil (STI)?
Helical Coil plug gages are used to check threaded holes prior to inserting a

nsert (STI).
•
How can I lengthen the life of my gage?
A longer gage life can be obtained by making sure the gages are handled and stored properly. Gages should be
handled like any precision tool or measuring device that is required to inspect close tolerances. Mishandling and
poor storage can cause nicks or other deformities which will destroy the gage. When storing gages make sure the
gage surfaces are protected and lubricated to prevent corrosion.
